Specific embodiment
As shown in Figure 1-Figure 3, in order to improve the heat dissipation effect of this product, a kind of current tester of reclosing breaker
Structure, including the zero sequence current mutual inductor 100 being arranged in breaker and four identical electric conductors 200, zero sequence current mutual inductor
100 have the hole 110 that passes through for electric conductor 200, and the electric conductor 200 passes through the hole 110 of zero sequence current mutual inductor 100, and four
The shape of a electric conductor 200, size uniformity cause, and electric conductor 200 passes through the hole 110 of zero sequence current mutual inductor 100, due to electric conductor
There are spacing between 200, so its heat dissipation effect can get a promotion, four 200 spacing of electric conductor are equal to be aligned across zero sequence electricity
The hole 110 of current transformer 100.
In order to reduce consumables cost and reduce resistance, the electric conductor 200 includes rear conductor 210 and joint cover 220, and
Conductor 210 is an integral structure with joint cover 220 afterwards, and traditional rear conductor 210 is connected by screw to joint cover 220, installation
Complexity, and resistance between the two is improved, by the way that rear conductor 210 and joint cover 220 are arranged to integral structure, reduce
Consumables cost, simple installation procedure, reduces contact and connection resistance and galvanic circle resistance, reduces product temperature rise, improves
The performance of product.
In order to improve product testing effect, the rear conductor 210 has upper surface 211 and lower perspective plane, and rear conductor
210 upper surface 211 is in same plane, and the lower perspective plane of rear conductor 210 is in same plane, guarantees each rear conductor
210 it is in the same size, spacing is consistent, makes rear conductor 210 is contour to be mounted in pedestal 300.
In order to improve the detection effect of this product, the hole 110 of the zero sequence current mutual inductor 100 have upper hole wall, under
Hole wall 111, left hole wall 112 and right hole wall 113, upper hole wall, lower hole wall 111, upper surface 211, lower perspective plane are arranged in parallel,
Spacing afterwards between 210 upper and lower ends of conductor and the 110 wall upper and lower ends of hole of zero sequence current mutual inductor 100 is identical, guarantees its inspection
Stability is surveyed, lower perspective plane refers to the lower surface of rear conductor 210, due to that can not show in figure, so can only pass through projection
Mode embody, so referred to as perspective plane.
In order to improve the detection effect of zero sequence current mutual inductor 100, the left hole wall 112 and right hole wall 113 are arc
Structure, arcuate structure is more preferable compared to right-angle structure effect, because the spacing between cambered surface and rear conductor 210 is essentially identical, and
Right-angle structure is since maximum spacing and minimum spacing gap are big, so detection effect is bad.
In order to which conductor 210 after guaranteeing and joint cover 220 can be assemblied on pedestal 300, the rear conductor 210 be coupled
It is equipped with several mounting holes 240 on plate 220, is coupled by mounting hole 240 and the inserting column of pedestal 300, easy for installation, structure
Simply, but this is one of mounting means, can also install, not repeated excessively this by other means.
It further include pedestal 300, institute to fix the matching relationship between zero sequence current mutual inductor 100 and electric conductor 200
The zero sequence current mutual inductor 100 stated laterally is assemblied in pedestal 300, and the electric conductor 200 is longitudinal to be assemblied in pedestal 300,
Pedestal 300 is that this field is conventional for fixing zero sequence current mutual inductor 100 and electric conductor 200 and other component, other component
Technology is not done this structure and is excessively repeated.
It is assemblied in pedestal 300 to guarantee that electric conductor 200 can be stablized, after the pedestal 300 is inserted by inserting column
Electric conductor 200 is fixed in the mounting hole 110 of conductor 210 and joint cover 220, is assembled by this way, structure is simple, assembles effect
Good, electric conductor 200 is not easy to loosen.
When in order to guarantee overload and short circuit current by joint cover 220, it can be monitored to, further include current transformer 400,
The current transformer 400 is assemblied in the position of the corresponding joint cover 220 of pedestal 300, when overload and short circuit current pass through connection
When plate 220,400 sampled signal feedback controller of current transformer carries out trip action.
Above-described parallel, same plane etc. is only the parallel and plane on geometric meaning, in actual production may
It can only be said almost parallel or flat because leading to not the problems such as machining accuracy or assembly precision to realize absolute parallel
Face.
